The Anker SoundBuds Curve Upgraded 2019 feel quite stable in the ear thanks to their ear-hook design, making them a great option for sports. There are three sizes of stability fins included in the box, which should help them stay in your ears even during more intense workout sessions. Unfortunately, the earbuds may slip out of your ear canal from time to time, and while they won’t fall right out of your ear, the change in the seal may alter the sound. If you prefer a truly wireless design within the same price range, check out the SoundPeats TrueFree.
